The effectiveness of the dust particles of the flask in the apparatus of counter-swirling flows

In this research was studied gathering efficiency and breakthrough of flask dust particles in industrial plants. The experiments were carried out on devices with counter swirling flows with various modifications and diameters of 150, 400, 600, and 800 mm. Analyzed and graphically presented the dependences of particle breakthrough on tghe devices size. The breakthrough effect in small inertial VZP devices was investigated, also the construction of VZP device was designed and experimentaly tested under operating conditions in terms of productivity and energy losses close to standard devices, but excluding the breakthrough effect of larger particles. Recommendations are given for the device usage on counter swirling flows with the best characteristics for capturing flask dust particles.
